Organizations Disable (or leave it unconfigured) only when they rely on high-mobility environments or ancient WINS-less setups. Disable is the default value of this policy.

Organizations Enable this policy to prevent a specific type of Denial of Service (DoS) and Spoofing attack. To enable this policy, click on the next button to continue.

Before completing the policy creation, you can review each tab to avoid misconfiguration or policy failure. After verifying all the details, click on the Create Button. After creating the policy, you will get a success message.
